Lake Cumberland has been known to humble even the best fishermen so don't worry yourself to much about getting skunked...yeah it's a bummer but that's how Lake Cumberland can be...there are others on this site that fish this lake more than me so they will be able to help you out a lot more with some information.

As for Jr losing interest...the other two places besides Lake Cumberland that I would take him is on a wading trip to the Cumberland River for trout (waders, light tackle, 6lb test, 1/4 oz lures and a nice low flow makes for some exciting catching)....and I would also take him to Dale Hollow. Both of these waters offer some real nice fishing, and his odds of catching a fish might be a little more in his favor. But as with all fishing, even these two waters can have their days in the barrel. Good luck and let us know how you do!
